Hello I am using MCUXpresso IDE, version v10.1.0 [Build 589] [2017-11-14] with an MIMXRT1050-EVK SDK, version 2.3.0 (2017-11-16). I was previously using a Rev. A3 of the MIMXRT1050-EVK and was able to use the OpenSDA interface under Ubuntu Linux, however, I recently two new Rev. A4 EVK boards and they do not enumerate under Linux but do enumerate under OSX. Unfortunately MCUXpresso for OSX appears to be lagging the main releases and does not yet support the RT1050.
On a whim I have tried loading new OpenSDA firmware from this link but it does not solve the enumeration issue.
I am aware of the usb power issue mentioned here but the modifications do not resolve this issue.
Any insight into this issue would be appreciated, thanks.
did you test the board by IAR? any result? I don't have A4 board to test for you, so pls debug by IAR first, then share the result.
and where do you download your code? flash or Ram?
